Blynk Server 0.28.4-SNAPSHOT successfully started.
All server output is stored in folder '/home/pi/Blynk' file.
Generating own initial certificates...
Error during certificate generation.
Network error

And server not work.

Seems like your user has not access to folder you are running blynk server on.

EDIT. Logs are created under /home/pi/logs folder.

Red_Cat · November 15, 2017, 7:21pm

I’m starting Blynk from /home/pi/Blynk folder as user “pi”.
set “pi@rpi:~/Blynk $ chmod 755 Blynk -R”
I have full access to folder. Logs file not created because server not started properly.
The problem has appeared recently, after transition to server-0.28.5-java8 version. Return to the previous version of the result did not bring.

Log you attached here shows me that problem is not with Blynk folder, but with /home/pi/logs folder.

Red_Cat · November 15, 2017, 8:13pm

/home/pi/logs folder exist and set pi@rpi:~ $ chmod 755 logs -R
Inside folder have’t current log files.

Dmitriy · November 15, 2017, 8:23pm

Try to run server from /home/pi folder. Does that help?

Red_Cat · November 15, 2017, 8:55pm

Yep, server started…

But why?

Dmitriy · November 15, 2017, 9:06pm

Probably because logs folder in your case was created in folder Blynk.

Red_Cat · November 17, 2017, 5:47pm

Thx, Dmitriy!
